A client is ordered to receive 4 g of a medication. The pharmacy has the medication available in a concentration of 160 mg per 5 mL. How many mL should the client receive?
The Correct Answer is ["125"]
To calculate the amount of mL that the client should receive, we need to use the formula:
mL = (g * 5 mL) / mg
where g is the ordered dose of the medication, mg is the concentration of the medication, and mL is the volume of the solution.
Plugging in the given values, we get:
mL = (4 g * 5 mL) / 160 mg
Simplifying, we get:
mL = 0.125 g/mL
Multiplying by 1000 to convert grams to milligrams, we get:
mL = 125 mg/mL
Therefore, the client should receive 125 mL of the solution.

Correct Answer is ["B","C","D","E"]
Explanation
A. Administer antibiotics
Administering antibiotics is not a direct intervention for preventing atelectasis. Antibiotics are typically prescribed to treat bacterial infections, and atelectasis is more related to lung collapse or incomplete lung expansion.
B. Encourage increased oral fluid intake
Adequate hydration is important for maintaining the moisture of respiratory secretions. This helps prevent mucus from becoming thick and sticky, making it easier for the patient to cough and clear the airways.
C. Early mobilization after surgery
Early mobilization, including activities such as getting out of bed and walking, helps improve lung expansion. It promotes better ventilation and prevents areas of the lungs from collapsing, reducing the risk of atelectasis.
D. Frequent turning of the patient
Turning the patient regularly is crucial for preventing pooling of respiratory secretions in dependent areas of the lungs. By changing the patient's position, nurses can facilitate drainage and ventilation throughout the lungs, minimizing the risk of atelectasis.
E. Use of incentive spirometry
Incentive spirometry is a breathing exercise device that encourages the patient to take slow, deep breaths. This helps expand the lungs and prevents atelectasis by maintaining lung volume and promoting alveolar recruitment.
Correct Answer is C
Explanation
A. Partial non-rebreathing mask:
This mask delivers higher concentrations of oxygen than a nasal cannula. It has a reservoir bag that allows the client to rebreathe some exhaled air, increasing the oxygen concentration delivered. However, it may not be necessary for a client with mild shortness of breath and slightly reduced oxygen saturation.
B. Simple (Oxy Plus) mask:
The simple mask provides a higher concentration of oxygen than a nasal cannula but lacks the reservoir bag found in the non-rebreathing mask. It is generally used for moderate oxygen needs. However, it might be more than what is required for a client with mild shortness of breath and slightly reduced oxygen saturation.
C. Nasal cannula:
Nasal cannulas are commonly used for clients with mild respiratory distress. They deliver a lower to moderate concentration of oxygen and are well-tolerated by most clients. They are suitable for individuals with mild shortness of breath and can be adjusted based on the required flow rate.
D. Non-rebreathing mask:
The non-rebreathing mask provides the highest concentration of oxygen among the options listed. It includes a reservoir bag to deliver a higher oxygen concentration. It is typically reserved for clients with higher oxygen requirements. For a client with mild shortness of breath and slightly reduced oxygen saturation, this may be more than necessary.
